Sadly, I contacted Nissan USA and they said that they have no way of answering technical questions and we will just have to go to the dealers for all technical answers. I suppose I could call several dealer and see what their answers will be but seriously? This means I have no way of getting definitive answers since I can't really trust the dealer when their recommendation deviates from the manual.

Getting back to the subject of when to change, is the deterioration rating a good indicator of when to change? The reason is that the car isn't driven all that much and is not likely to hit 30K any time soon even though it's 5 years old. I need to know if the CVT fluid needs changing. Based on the dealer's recommendation, it should have been changed 2 years ago (3 year/30K) or if I followed the premium schedule in the manual next year at 6 yr/60,000 miles. Changing it isn't cheap, so I would rather avoid it if it's not actually going to prevent anything.

I could call around and find a dealer who could "test" the cvt fluid.

The fluid is definitely going to get particulate in it as the belt and other parts wear. That is pretty much a function of the number or miles driven (or abuse). It's a crap shoot as to when this becomes a problem.

You WERE told about the dealers and higher up...............The OEMs figured out long ago that too much info back to the customers killed their dealer work throughputs. Why you don't get free service manuals with every new car sale. They view after the sale maintenance as theirs only and why CVT gets maintained the way it does now. A dumber customer is better and the way they like it.

Fluid at some point needs changing even with time only, it slowly develops acids in it from the exposure to metal parts and humidity. Where low temperature sludge comes from. Transmissions are not as bad about that as engines are though.

I have 2007 Versa hatchback with CVT with 251,000 Km (156,000 Miles). I changed my CVT oil twice at 100,000 and 200,000 km. I have not experience the limp mode which people are talking about. I may be the lucky one without issue with my CVT. I had problem with the front springs, steering wheel clockspring and lower control arm.

I had a moment of clarity while talking with the developer of CvtZ50 app, the android app that can pair up with a ELM327 to display cvt info. He pointed out that the deterioration value should not be used to judge when to change CVT fluid, but more of a way to gauge in a relative scale how much deterioration you get from heat. He suggest the best way to judge would be to visually inspect it. Unfortunately, I don't think you can just pull out a dip stick and check it.

I am now thinking of just replacing the fluid after this year, which would mean the car is 6 years old and nowhere near 30K, but perhaps it would be a good idea to maintain it due to possible contamination. We could change earlier if the dealer can show that the fluid is a bad color.

You can indeed look at fluid color as a temperature exposure device. The fluid gets both darker and dirty looking. There is not so much dye to tell actual burning like old school red fluids had, the fluid actually changed color on those but if you apply the same color change direction to CVT fluid that should work too. Take my Altima, the fluid is very faint bluish or blue-green but beginning to get dirty like gray or black added to it. The color shows best wiped on a clean paper towel to show it against the white.

You can likely add a dipstick where none was at and what I did on that car.

Looking at fluid is not strictly a dealer ability, any fool can do it. Why I use no dealers at all and now for 45+ years. They are most commonly NOT your friend there regardless of what they say.

My dealer told me on my 2018 Versa the transmission is sealed and no way to change it. Both the salesman and service manager told me that. The service manager said there isn't even a drain plug on them. I wish there was a good video out there showing how to do it along with flushing the torque converter out.

There are a number of Youtube videos that show how to do it at home, but this is one of those issues that I would let the dealer handle. The information below gives you some information:

They haven't put drain plugs on most ATX pans for like 50 years now, you can't let that stop you.

Regardless, changing ALL of the fluid on one of these can be a challenge.

The dealer there was a liar, no other way to put it. There is no such thing as a sealed transmission and never has been.
